# What is the meaning of pH and why is the H a capital letter?

The abbreviation pH means "potential of Hydrogen" where capital H is the symbol for the element hydrogen.

### Why do you write pH p small letter and H in caps?

H in pH means hydrogen and the symbol for hydrogen is a capital H so that is why it is in capitals and the p is not.

pH refers to the relative concentration of H+ ions in solution.

### What does a low pH mean in terms of H plus ions?

A low pH is acidic, meaning there is a higher concentration of H+ ions.

### What ion does the pH scale measure?

H is for Hydrogen. p[H] is a messurement for Hydrogen-ion koncentration and pH for the activity to be correct. the p is for the -log called anti-log (log=logarithm) meaning the exponent (number of the potense) of H ions. pH = -log [H+] or [H+] = 10-pH

### Why is there a lower case p before a capital letter H in the scientific symbol pH?

yes and it means the negative logarithim to base 10

### What is the scientific meaning of pH?

pH is the measure of the acidity or alkalinity of a solution. It is formally a measure of the activity of dissolved hydrogen ions (H+) in the solution.

### What does the h stand for in pH scale?

The letter h in pH scale stands for Hydrogen. The proper description for the name ph. is potential of Hydrogen.

pH=-lg[H+] [H+]=10-pH With pH=2.0: Corrected: [H+]= 10-pH = 10-2.0 = 0.010 M HCL

### Why is there a lowercase p and a capital H in the pH scale?

the p stands for "negative logarithm" or -log, a mathematical function. the H is the chemical symbol for hydrogen, in the case it represent the concentration of hydrogen ions (H+) in a solution. pH is the negative logarithm of the hydrogen ion concentration or -log[H+]. This is a good measurement of acidity or alkalinity as acids increase the H+ concentration and bases decrease it.

### What is the formula to calculate pH?

pH = -log[H+] (pH equals the negative log of the molar concentration of H+)

### Does and acid with a pH of 1 or a pH of 3 have a greater H concentration?

[OH-][H+] = 10-14 [H+] = 10-14/0.01 [H+] = 1.0 Ã— 10-12 pH = -log[H+] pH = -log 1.0 Ã— 10-12 pH = 12

### What is the relationship of pH to H plus?

pH=-log[H+] In other words, pH is the negative logarithm (base 10) of the concentration of H+ ions

### What state and its capital both have names that begin with the letter H?

The state of Hawaii and its capital Honolulu both start with H.

### What is pH and what does it tell you?

definition : pH= - log10 [H+] ; [H+] denotes the concentration of H+ ions in the solution..

### A solution with a pH value smaller than 7 would be a?

An acid; pH is a measure of the [H+] of a system. A solution with high [H+] is acidic, and has a low pH, according to the equation: pH = -log10([H+])

### what is pH and what is the pH?

The pH is a measure of the activity of the ion H+; pH is an indication for acidity or basicity.

### How does the pH scale apply to acids and bases?

The pH scale exists from 0 to 14.The less the pH, more is the solution acidic and more the pH the more it is basic. 7 indicates neutral. * * * The pH scale measures hydrogen ion (H+) concentration in a substance. For example, water (H2O) has a neutral pH of 7. Some of the water molecules will naturally dissociate (or break apart), forming hydrogen ions (H+) and hydroxyl ions (OH-). So you have positive… Read More

### What is the H concentration in an acid with pH 4.6?

By definition, pH = -log[H+] so [H+] = invlog(pH) = 10-pH = 10-4.6 (or invlog[-4.6]) = 2.5*10-5 mol/L

### How does the H plus concentration of solution with a pH of 5 compare to a solution with a pH of 3?

The H+ concentration of a solution with a pH of 3 is 100 times more concentrated than the H+ concentration of a solution with a pH of 5. The concentration of H+ is always ten times more than the previous pH. So going from a pH of 6 to a pH of 5, the concentration of H+ is multiplied by 10, and the acid is ten times stronge.

### How do you find the value of H3O when you have the pH value?

pH equal to the minus log value of H+ concentration.Equation for that is pH= -log[H+]

### What is the pH of an aqueous solution if the H 0.001 M?

### Relation between pH value and H ions?

pH = -log10[H+] (pH is the minus log of the hydrogen ion concentration) A low pH value means lots of H+ eg in sulphuric acid, pH 2 or 3. A high pH means less H+ eg if the solution is alkaline, pH 13-14. On your calculator, it's easy to get from H+ to pH. To get from pH to H+ you need to either do 10-pH or do shift log (minus number).
